Why yes. I played a CN prettyboy sorcerer who dressed in tattered yellow rags and had a taste for wearing masks. His 'look' was kinda a fusion of the King in yellow and and a Street fighter character. i commissioned a sketch and even slapped a mini together for him.
I might have had a short-lived cleric that might have worn a yellow cloak, à la Aasimar Favored Soul, but, in general, my guys tend to stay away from really flashy colors.
Imagine that you are poor kobold hunter, raiding hard to feed your family.
You come home from long day of pillaging to relax. You sit down in your
small grimy cave and begin to unwind and..........BAM! Some adventurer
comes crashing in and splits your head open with a battle axe!
Now I ask you, do you really care what color clothes that son of a harpy is wearing?
